41    @brief
42        The MobileEntity is a derived class from @ref orxonox::WorldEntity and @ref orxonox::Tickable. It is supposed to be the base class of
43        @ref orxonox::MovableEntity and @ref orxonox::ControllableEntity. You will never need to instanciate a MobileEntity directly.
44        Use only its derivatives.
45        In addition to the functionalities of the @ref orxonox::WorldEntity this class has a linear and angular velocity and a linear and angular acceleration.
46        Every time the @see tick function is called the linear acceleration is multiplied by the time since the last call of tick and then added to the
47        linear velocity. Then the linear velocity is multiplied by the time since the last call of tick and then added to the position. The same happens with
48        the angular acceleration and velocity. With this procedure MobileEntities can change their position and orientation with time.
49
50        A MobileEntity can only have the collisition type WorldEntity::None, WorldEntity::Dynamic or WorldEntity::Kinematic. The collsion type WorldEntity::Static is illegal.
